EFIS to Celebrate 50th Anniversary with Strong Presence at IUIS 2025 Congress in Vienna

The European Federation of Immunological Societies (EFIS) is proud to mark its 50th anniversary with a dynamic and multifaceted presence at the IUIS 2025 Congress. In celebration of five decades of advancing immunological research and collaboration across Europe, EFIS is organizing a series of high-profile events and activities, reflecting both its rich legacy and its ongoing commitment to the global immunology community.

A scientific highlight will be the EFIS Guest Symposium, titled “Immunity Mediated by Innate Lymphocytes”. This session will feature leading European experts in the field and spotlight cutting-edge insights into innate lymphocyte biology, underscoring Europe's strong contributions to this rapidly evolving area.

EFIS will also host the prestigious Lifetime Achievement Award Lecture and Ceremony, honoring Professor Klaus Rajewsky for his extraordinary 60-year career in immunology. Professor Rajewsky’s pioneering work has shaped modern immunology and inspired generations of scientists; the award recognizes his enduring impact on the field.

In addition, EFIS will proudly present the ACTERIA Foundation Early Career Research Awards at the Congress, highlighting exceptional achievements by young investigators in immunology and allergology.

Throughout the Congress, EFIS will welcome members and attendees at its dedicated booth in the exhibition hall, serving as a hub for networking, information, and community engagement. The booth will also be a space to connect with this year’s EFIS-EJI Travel Grant recipients. Continuing a long-standing tradition of supporting young scientists, EFIS and the European Journal of Immunology (EJI) have provided travel grants to nearly 100 early-career researchers to attend IUIS 2025. EFIS is proud to support their participation and looks forward to celebrating their achievements in person.

Join EFIS at IUIS 2025 as we commemorate 50 years of advancing immunology and fostering the next generation of researchers across Europe and beyond.

EFIS Society News SFI organizes its 56th Annual Meeting The 56th Annual Meeting of the French Society for Immunology (SFI) will take place from 12 to 14 November 2025 at the Cité des Sciences et de l’Industrie in Paris. This key event will highlight the latest advancements in fundamental, applied, and medical immunology through plenary sessions, parallel talks, and workshops. A special emphasis will be placed on Young Immunologists, giving students and postdoctoral researchers a platform to present their work. Awards will be given for outstanding oral and poster presentations.

The First Adriatic Immunology Symposium, featuring the EFIS on Tour initiative, was successfully hosted by the Croatian Immunological Society at the University of Rijeka on June 27, 2025. The event brought together 80 researchers from the region, offering a vibrant platform for scientific exchange and collaboration. Attendees engaged in insightful presentations by leading immunologists, covering a broad range of topics including T cell biology, cancer immunotherapy, immune metabolism, autoimmunity, and host-pathogen interactions. The symposium also highlighted strengthening regional scientific networks and fostering future cooperation.

Furthermore, on June 28, EFIS held its second Board Meeting of 2025 in Rijeka. A key focus of the meeting was planning EFIS’s presence and activities at the upcoming IUIS 2025 congress in Vienna, underscoring the federation’s commitment to supporting international immunology engagement and visibility. EFIS Board also welcomed representatives of the Croatian Immunology Society (HID) at their meeting.

This joint occasion marked a significant milestone for both regional and European immunology, reinforcing scientific ties across the Adriatic and beyond.
